A spoof of the superhero craze of the late 1960s, this episode gets under way when several businessmen are found clawed to death. All evidence seems to point to a comic-strip character called The Winged Avenger -- but that's impossible, isn't it? While trying to get to the truth of the matter, Steed and Emma find themselves besieged by characters who seem to have sprung full-grown from the American series Batman (there's even a "BANG! POW!" fight sequence, performed with cardboard cutouts of comic-strip "balloons"). Written by Richard Harris, "The Winged Avenger" first aired in England on February 18, 1967 -- the day after its American TV debut. ~ Hal Erickson, Rovi
